Retrieving elements from an associative array

Hi, I am wondering if anyone knows how to get the value specified by a certain key of an associative array. Meaning if the user passes something like this: start_html( array("BGCOLOR" => "FFFFFF", "TEXT" => "000000") ); How will I be able to retrieve the BGCOLOR element from within my function (This is a Zend API question). I know there is a zend_hash_get_current_key function which gets the current key of the array, how would I get the current value relating to that key. Thanks, Sterling Hughes sterling@designmultimedia.com
